The perimeter of the following figures-
Perimeter = sum of all sides 

Therefore, 
(a) Perimeter = 4 cm + 2cm +1 cm +5cm = 12 cm

(b) Perimeter = 23 cm + 35 cm + 40cm + 35cm = 133 cm

(c) Required perimeter = 15cm + 15 cm + 15 cm +15 cm = 60 cm

(d) Required perimeter= (4 + 4 + 4 + 4 + 4) cm = 20 cm

(e) Perimeter = 4cm + 0.5 cm +2.5cm +2.5cm + 0.5cm +4cm +1cm = 15cm

(f) Perimeter = Sum of all sides = 4\times(4cm) + 4\times(1 cm) + 8\times(3 cm) + 4\times(2cm) = (16 + 4 + 24 + 8)cm =52 cm
